Detailed Description

The following describes a drive system according to an embodiment of the present invention. It should be appreciated, however, that the embodiments of the invention provide many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The particular embodiments disclosed are illustrative only of the use of the invention in particular ways, and are not intended to limit the scope of the invention.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

The foregoing and other features, aspects and utilities of the present invention will be apparent from the following more particular description of a preferred embodiment of the invention as illustrated in the accompanying drawings. Directional terms as referred to in the following examples, for example: up, down, left, right, front or rear, etc., are directions with reference to the attached drawings only. Therefore, the directional terms used in the embodiments are used for description and are not intended to limit the present invention.

Referring to fig. 1 and fig. 2, fig. 1 is a perspective view of a driving system according to an embodiment of the present invention combined with first and second optical elements L1 and L2, and fig. 2 is a perspective view of the first and second modules 1 and 2 of fig. 1 with the housings H1 and H2 and the image sensing units Q1 and Q2 removed.

As shown in fig. 1 and fig. 2, the driving system of the present embodiment mainly includes a first module 1 and a second module 2 adjacently disposed along the X-axis direction (first axial direction), wherein an image sensing unit Q1 is disposed at the bottom side of the first module 1, and an image sensing unit Q2 is disposed at the bottom side of the second module 2. For example, the first and second modules 1 and 2 may have different thicknesses in the Z-axis direction and may be used to respectively carry the first and second optical elements L1 and L2, wherein the first and second optical elements L1 and L2 are, for example, optical lenses (optical lenses) having different optical effective diameters (optical effective diameters) or qualities.

The driving system of the present embodiment can form a dual-lens camera unit with the first and second optical elements L1 and L2, wherein the camera unit can be disposed inside a portable electronic device (such as a mobile phone or a tablet computer) for performing functions of taking pictures or photographing.

For example, the first and second modules 1 and 2 may include a Voice Coil Motor (VCM) for driving the first and second Optical elements L1 and L2 to move relative to the housings H1 and H2, respectively, so as to achieve auto-focusing (AF) or Optical Image Stabilization (OIS) functions.

As can be seen from fig. 2, frames F1 and F2 fixed inside housings H1 and H2 are respectively provided in the first and second modules 1 and 2, wherein the frames F1 and F2 are respectively connected to the bearings LH1 and LH2 through reeds R1 and R2. When assembled, first and second optical assemblies L1, L2 may be disposed in carriers LH1, LH2 (first and second movable portions), and the assembled first and second optical assemblies L1, L2 and carriers LH1, LH may move relative to frames F1, F2 and housings H1, H2 (first and second fixed portions).

On the other hand, at least a first magnetic assembly M1 and a second magnetic assembly M2 fixed to the frames F1 and F2 are further disposed inside the first and second modules 1 and 2, respectively. In this embodiment, the first and second magnetic assemblies M1, M2 are, for example, magnets, and when an external circuit passes current to coils (not shown) disposed on the bearings LH1, LH2, the coils on the bearing LH1 and the first magnetic assembly M1 generate an electromagnetic driving force to drive the bearing LH1 to move relative to the housing H1 and the frame F1; similarly, the coil on the carrier LH2 and the second magnetic assembly M2 can generate an electromagnetic driving force to drive the carrier LH2 to move relative to the housing H2 and the frame F2, so that the first and second modules 1 and 2 can have functions of Auto Focus (AF) or optical hand shock protection (OIS).

In addition, in the present embodiment, a first connection portion P1 and a second connection portion P2 are respectively disposed at the bottom sides of the first module 1 and the second module 2, wherein the first connection portion P1 is located at the first side S1 of the first module 1 for electrically connecting the coil on the supporting element LH1 to an external circuit, and the second connection portion P2 is located at the second side S2 of the second module 2 for electrically connecting the coil on the supporting element LH2 to the external circuit.

It should be noted that, in the present embodiment, by making the first and second sides S1, S2 adjacent to each other and located on the same side of the driving system, the first and second connecting portions P1, P2 can be electrically connected to the external circuit in the same welding or soldering process without turning the driving system, so that the assembly efficiency of the driving system can be greatly improved.

Referring to fig. 3, fig. 3 shows a schematic diagram of a relative position relationship between the first and second optical elements L1 and L2 and the housings H1 and H2 of the first and second modules 1 and 2 and the first and second magnetic elements M1 and M2 inside the first and second optical elements.

As shown in fig. 3, a pair of first magnetic assemblies M1 and a pair of second magnetic assemblies M2 are respectively disposed inside the first and second modules 1 and 2, wherein the first magnetic assembly M1 and the coil disposed on the supporting member LH1 can form a first driving assembly, and the second magnetic assembly M2 and the coil disposed on the supporting member LH2 can form a second driving assembly, so as to respectively drive the supporting members LH1 and LH2 and the first and second optical assemblies L1 and L2 disposed therein to move by magnetic force.

As shown in fig. 3, an L-shaped circuit board C is disposed inside the first module 1, and an electronic component C1 and a filter component C2 are disposed on the circuit board C, wherein the electronic component C1 and the filter component C2 are disposed on a third side S3 of the first module 1.

For example, the electronic component C1 may be a position sensor, an inertial sensor, an integrated circuit component or a passive component; in the embodiment, the electronic component C1 is a Hall effect sensor (Hall effect sensor) for sensing the movement of the bearing member LH1 (the first movable portion) relative to the housing H1 (the first fixed portion), and since the mass of the second optical component L2 is smaller than that of the first optical component L1, the Hall effect sensor is disposed inside the first module 1, so that accurate closed-loop control (closed-loop control) can be performed on the first optical component L1 with larger mass.

In practical applications, the electronic component C1 may also be electrically connected to a control circuit (not shown), wherein the control circuit may output different driving signals to the coils (first and second driving components) of the bearings LH1 and LH2 to control the movement of the bearings LH1 and LH2 relative to the housings H1 and H2.

It should be noted that the third side S3 of the first module 1 faces a fourth side S4 of the second module 2, wherein the first magnetic element M1 is disposed on the other side of the first module 1 different from the third side S3, and the second magnetic element M2 is disposed on the other side of the second module 2 different from the fourth side S4. In this way, the electronic component C1 can be positioned between the first and second optical components L1, L2 to effectively utilize the space, and can also be prevented from being subjected to the electromagnetic interference generated by the first and second magnetic components M1, M2 or the electronic components outside the driving system.

Referring to fig. 4, fig. 4 is a side view of a driving system according to another embodiment of the present invention, combined with first and second optical elements L1 and L2. As shown in fig. 4, in the present embodiment, an electronic component C3 is mainly disposed on the image sensing unit Q1 at the bottom side of the first module 1, wherein the electronic component C3 is electrically connected to the image sensing unit Q1, and the electronic component C3 and the first and second modules 1 and 2 do not overlap each other when viewed along a horizontal direction (Y-axis direction).

In addition, when viewed along a vertical direction (Z-axis direction) parallel to the optical axes of the first and second optical elements L1 and L2, the electronic component C3 partially overlaps the first or second module 1 or 2, thereby fully utilizing the space under the first or second module 1 or 2 and achieving miniaturization of the driving system. For example, the aforementioned electronic component C3 may be a position sensor (e.g., a hall effect sensor), an inertial sensor, an integrated circuit component, or a passive component.

Referring to fig. 5, fig. 5 is a perspective view of a driving system according to another embodiment of the present invention, combined with first and second optical elements L1, L2, and L3. The embodiment of fig. 5 differs from the embodiment of fig. 1 mainly in that: in fig. 5, a third module 3 and a third optical assembly L3 are additionally provided, wherein the first, second and

third modules

1, 2 and 3 are arranged along the X-axis direction (first axial direction), and the optical effective diameter of the second optical assembly L2 is larger than that of the third optical assembly L3.

As shown in fig. 5, the third module 3 has a housing H3 and a supporting member LH3 for supporting the third optical element L3, and an image sensing unit Q3 is further disposed below the housing H3; carrier LH3 can be connected to housing H3 via a reed, and at least a third magnetic assembly M3 (shown in fig. 6) is disposed inside housing H3, and the third magnetic assembly M3 and a coil (not shown) disposed on carrier LH3 can constitute a third driving assembly.

It should be understood that when an external circuit passes current to the coil on the carrier LH3, the coil on the carrier LH3 and the third magnetic assembly M3 can generate an electromagnetic driving force to drive the carrier LH3 (the third movable portion) to move relative to the housing H3 (the third fixed portion), so that the third module 3 can have an auto-focusing (AF) or optical hand-shake (OIS) function.

In the present embodiment, a first connection portion P1, a second connection portion P2 and a third connection portion P3 are respectively disposed at the sides of the first, second and

third modules

1, 2 and 3 for electrically connecting to external circuits, wherein the first, second and third connection portions P1, P2 and P3 are located at the same side of the driving system; therefore, the first, second and third connecting portions P1, P2 and P3 can be electrically connected with an external circuit in the same welding or soldering process without turning the driving system, thereby greatly improving the assembly efficiency of the driving system.

Referring to fig. 6, fig. 6 is a schematic diagram illustrating a relative position relationship of the first, second, and third magnetic elements M1, M2, M3 in the first, second, and

third modules

1, 2, 3 after combination. As shown in fig. 6, the third side S3 of the first module 1 faces the fourth side S4 of the second module 2, and the fifth side S5 of the third module 3 faces the sixth side S6 of the second module 2, wherein the fifth side S5 of the third module 3 is parallel to the third side S3 of the first module 1.

It should be noted that the circuit board C having the electronic component C1 and the filter component C2 is disposed on the third side S3 of the first module 1, and the two first magnetic components M1 are disposed on the other two sides of the first module 1 different from the third side S3, so that the circuit board C can be effectively prevented from being magnetically interfered by the first magnetic components M1.

Similarly, as can be seen from fig. 6, two second magnetic assemblies M2 are disposed on two other sides of the second module 2 different from the fourth side S4, so as to prevent the circuit board C from being magnetically interfered by the second magnetic assemblies M2.

It should be appreciated that since no magnetic element is provided at the sixth side S6 of the second module 2, the third magnetic element M3 may be provided at either side of the third module 3. In the present embodiment, the four third magnetic elements M3 are respectively disposed on four sides of the third module 3, so as to enhance the electromagnetic driving force to the supporting member LH3 and the third optical element L3.

Referring to fig. 7, fig. 7 is a schematic diagram illustrating a relative position relationship of the first, second and third magnetic elements M1, M2 and M3 inside the first, second and

third modules

1, 2 and 3 according to another embodiment of the present invention after assembly. The main difference between the embodiment of fig. 7 and the embodiment of fig. 6 is that: the first module 1 is located between the second and

third modules

2 and 3, and the circuit board C having the electronic component C1 and the filter component C2 is located on a third side S3 of the first module 1 (facing the fourth side of the second module 2).

As shown in fig. 7, since the first magnetic assembly M1 is not disposed on the third side S3 of the first module 1, and the second magnetic assembly M2 is not disposed on the fourth side S4 of the second module 2, the circuit board C can be effectively prevented from being magnetically interfered by the first and second magnetic assemblies M1 and M2. On the other hand, the third magnetic element M3 can be disposed on the fifth side S5 of the third module 3 without being magnetically interfered by the first magnetic element M1, wherein the fifth side S5 of the third module faces the first module 1.

Referring to fig. 8, fig. 8 is a side view of a driving system according to another embodiment of the present invention combined with first, second, and third optical elements L1, L2, and L3. As shown in fig. 8, the electronic element E may be disposed between the first and second optical elements L1 and L2, or may be disposed between the second and third optical elements L2 and L3 to fully utilize the space.

In the present embodiment, the electronic component E at least partially overlaps the first optical component L1, the second optical component L2 or the third optical component L3 when viewed along the X-axis direction (the first axis direction). For example, the electronic component E may include a hall effect sensor, an inertial sensor, an integrated circuit component, a light emitting component (e.g., a flash lamp), or a passive component.

It should be understood that the image sensing units Q1, Q2, Q3 of the present embodiment are respectively fixed on the bottom sides of the housings H1, H2, H3 and correspond to the first, second, third optical components L1, L2, L3, wherein the end surfaces a1, a2, A3 of the first, second, third optical components L1, L2, L3 respectively protrude out of the top surfaces H11, H21, H31 of the housings H1, H2, H3 and are located at substantially the same height (height difference is less than 0.5mm) in the Z-axis direction (vertical direction); however, the height positions of the image sensing units Q1, Q2, Q3 in the Z-axis direction are different, and by making the end surfaces a1, a2, A3 of the first, second, and third optical elements L1, L2, L3 having different lengths T1, T2, T3 flush with each other, the aberration generated when the image is captured can be greatly reduced.

In addition, it can be seen from fig. 8 that the top surfaces H11, H21, H31 of the housings H1, H2, H3 are also different in height position, wherein a first distance d1, a second distance d2 and a third distance d3 are respectively provided between the end surfaces a1, a2, A3 of the first, second and third optical components L1, L2, L3 and the top surfaces H11, H21, H31 of the housings H1, H2, H3, wherein d2< d1< d 3.

Next, please refer to fig. 9 and 10, wherein fig. 9 is a perspective view of a driving system of another embodiment of the present invention combined with first, second, and third optical elements L1, L2, and L3 and disposed inside a fixing frame B, and fig. 10 is a schematic view of the fixing frame B in fig. 9.

As shown in fig. 9, the first, second and

third modules

1, 2 and 3 of the present embodiment are arranged in an L-shape, wherein the driving system further includes a fixing frame B, the fixing frame B is formed with a first frame surrounding the first module 1, a second frame surrounding the second module 2 and a third frame surrounding the third module 3, wherein a first gap B1 is formed between the first frame and the first module 1, a second gap B2 is formed between the second frame and the second module 2, and a third gap B3 is formed between the third frame and the third module 3.

When assembling, the first, second and

third modules

1, 2 and 3 can be placed inside the first, second and third frames of the fixing frame B, respectively, then the light sensing surfaces of the image sensing units Q1, Q2 and Q3 can be aligned in angle and parallel to each other, and then the adhesive is filled into the first, second and third gaps B1, B2 and B3, so that the first, second and

third modules

1, 2 and 3 can be stably positioned in the fixing frame B, thereby ensuring that the image sensing units Q1, Q2 and Q3 provide good imaging quality.

Referring to fig. 10 and fig. 11, fig. 11 is a schematic diagram showing a relative position relationship between the fixing frame B and the first, second and third magnetic elements M1, M2, M3 and the circuit board C inside the first, second and

third modules

1, 2 and 3 after they are combined.

As shown in fig. 10 and 11, a plurality of protruding portions BP are formed on the inner side of the fixing frame B of the present embodiment, and protrude toward the first, second, and

third modules

1, 2, and 3, respectively, so that the protruding portions BP can abut against the first, second, and

third modules

1, 2, and 3, respectively, during assembly, to facilitate positioning therebetween.

In addition, a circuit board C is disposed inside the first module 1 of the present embodiment, and an electronic component C1 and a filter component C2 are disposed on the circuit board C, wherein the electronic component C1 is, for example, a position sensor, which can be used to sense the movement of the bearing member LH1 (the first movable portion) inside the first module 1 relative to the housing H1 (the first fixed portion).

It should be noted that, when viewed in the protruding direction of the protruding portion BP, the edge of the protruding portion BP does not overlap with the position sensor C1 and the filter element C2, so that the position sensor C1 or the filter element C2 is prevented from being damaged by being pressed by the sharp edge of the protruding portion BP.

On the other hand, as can also be seen from fig. 11, the third side S3 of the first module 1 faces the fourth side S4 of the second module 2, the fifth side S5 of the third module 3 faces the sixth side S6 of the second module 2, the circuit board C provided with the electronic component C1 and the filter component C2 is disposed on the side of the first module 1 away from the second module 2, the fifth side S5 of the third module 3 is parallel to the first side S1 of the first module 1, and the first side S1 of the first module 1 and the second side S2 of the second module 2 are respectively provided with the first and second connecting portions P1 and P2 as shown in fig. 1.

It should be appreciated that, since the third magnetic element M3 is disposed on the fifth side S5 of the third module 3, the second magnetic element M2 is disposed on another side (e.g., the fourth side S4) of the second module 2 different from the sixth side S6, so as to avoid magnetic interference between the second and third magnetic elements M2, M3 due to too close distance.

In an embodiment, only two of the first, second, and

third modules

1, 2, and 3 may be disposed and the other one may be omitted, or the first, second, and

third modules

1, 2, and 3 may be arranged in the fixing frame B in a straight line.
